[Kazuhiro NISHIYAMA]

Public bug reported:

apt-show-versions 0.15 ignores version in jaunty-updates.

example:
% LANG=C apt-cache policy compiz
compiz:
  Installed: 1:0.8.2-0ubuntu8
  Candidate: 1:0.8.2-0ubuntu8.1
  Version table:
     1:0.8.2-0ubuntu8.1 0
        500 http://jp.archive.ubuntu.com jaunty-updates/main Packages
 *** 1:0.8.2-0ubuntu8 0
        500 http://jp.archive.ubuntu.com jaunty/main Packages
        100 /var/lib/dpkg/status
% apt-show-versions compiz      
compiz 1:0.8.2-0ubuntu8 installed: No available version in archive
%

When ubuntu, %releasenames has following keys and values:

%releasenames = {
          'archive.ubuntulinux.jp_ubuntu_dists_jaunty' => {
                                                            'Suite' => 'jaunty',
                                                            'Name' => 'jaunty',

                                                                  'Name' => 'jaunty-non-free',
                                                                  'Codename' => 'jaunty-non-free'

                                                           'Name' => 'jaunty',
                                                           'Codename' => 'jaunty'
                                                         },
          'dl.google.com_linux_deb_dists_stable' => {
                                                      'Suite' => 'stable',
                                                      'Name' => 'stable',
                                                      'Codename' => 'stable'
                                                    },
          'jp.archive.ubuntu.com_ubuntu_dists_jaunty-updates' => {
                                                                   'Suite' => 'jaunty-updates',
                                                                   'Name' => 'jaunty-updates',
                                                                   'Codename' => 'jaunty'
                                                                 },
          'archive.canonical.com_ubuntu_dists_jaunty' => {
                                                           'Suite' => 'jaunty',
                                                           'Name' => 'jaunty',
                                                           'Codename' => 'jaunty'
                                                         }
        };

And at following code in sub determine_pkgfile_release,
when $pkgfile eq 'jp.archive.ubuntu.com_ubuntu_dists_jaunty-updates_main_binary-i386_Packages',
it matches 'jp.archive.ubuntu.com_ubuntu_dists_jaunty-updates' and 'jp.archive.ubuntu.com_ubuntu_dists_jaunty'.
It looks that 'jp.archive.ubuntu.com_ubuntu_dists_jaunty' checked early,
then sub determine_pkgfile_release returns 'jaunty' even if it should be returns 'jaunty-updates'.

    foreach (keys %releasenames) {
        return $_ if ($_ eq substr($pkgfile, 0, length($_)));
    }
